Azure AD and AWX Integration

I am trying to set up authentication and authorization via Azure AD with AWX, versioin 3.0.1.0

Issue:

Azure AD OAUTH2 callback URL is grayed out with a red “crossed out” icon so I can’t enter the necessary URL. How do I fix this?

Question:
according to the Tower documentation, it looks like only usernames/emails can be entered into the query for Azure AD authentication, I would like to enter security groups instead so those groups are mapped to Team in AWX to provide authorization & authentication via AD, not AWX. Is this possible or do I need to use LDAP?
